AEROPLANE Filed April 9, 1928 2 Sheets-S`neet 2 By @M @1620A PatentedApi. 15, 1930 PATENT FFICIE ISAAC E. HANSON, CF OKLAHOMA CITY, OKLAHOMAAnnemans Application filed April 9, 1928. Serial No. 26S-,571.

p rI'he present invention relates generally to aeroplanes and has forits prime object lo provide means for preventing the formation of-ice onthe Wings of the aeroplane.

Other very important objects of the invention reside in the provision ofmeans whereby the heat generated by the exhaust of the engine of theaeroplane may be utilized to prevent the formation of the ice on thewings.

19 A still further very important object of the invengtionlresides inthe provision of an improvement of this nature which is simple in itsconstruction, inexpensive to install, strong and durable, and thoroughlyefficient 15 and reliable in use and otherwise Well adapted to thepurpose for which it is designed.

With the above and numerous other obv jects in view'as will appear asthe descrip tion proceeds, the invention resides in cer- 20 tain novelfeatures of construction and in the combination and arrangement of partsas will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a top plan View of an aeroplane embodying the features of myinvention.

Figure 2 is a front elevation thereof.

Figure 3 is a fragmentary side elevation thereof. am Figure 4 is asectional view through the air drum and exhaust pipe.

Figure 5f is a sectional View throughone of the Wings and the airchamber thereon, and

Figure 6 is a detail section taken through 35 one of the conduits.

Referring to the drawing in detail, it will be seen that the numeral 5denotes anaeroplane fuselage, having Wings 6 and 7 mounted thereon, inthe usual Well known manner. On the Wings 6 and 7 there are mountedrespectively'air chambers 8 and 9, formed of sheet metal. Pipes 1()connect the air chambers 8 and 9 together. Branches 11 lead inwardlyfrom the pipes 10 intermediate their ends and communicate with the drum12 disposed about exhaust manifolds 14 leading from the engine 15. Apipe 16 leads from the exhaust manifold along the top Aof the fuselage 5and terminates' adjacent the rear controls 17, to prevent the formationof ice thereon. The exhaust heating up the exhaust pipe 14 will heat theair in the drum 12 and cause it to circulate through branches 11 andpipes 10 into the chambers 8 and 9 which Will be -suiiciently heated toprevent the 5 formation of ice thereon in rainy and snowy Weather.

It is thought that the construction, utility and advantages of thisinvention will noW be quite apparent to those skilled in this artwithout a more detailed description thereof.

It is apparent that the present embodiment of the inventionlhas beendisclosed in considerable detail merely by Way of example, since inactual practice it will retain the fea tures of advantage enumerated asdesirable in the statement of the invention and the I, abovedescription.

It will be apparent that changes in the details of construction and inthe combination 1 and arrangement of parts may be resorted to, Withoutdeparting ,from the spirit and. scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. In an aeroplane of the class described,

a fuselage, a pair of Wings mounted on the fuselage, air chambers on theWings, pipes connecting the 4air chambers,branches lead- 5 ing inwardlyfrom the pipes, an exhaust pipe, a drum about the exhaust pipe withwhich the branches communicate. a pipe connected vvit-hfthe exhaust pipeand extending alongthe top of the fuselage rearwardly to as, terminateat the rear end thereof.

` 2. An aeroplane comprising a fuselage, an exhaust pipe in thefuselage, a drum disposed about the exhaust` pipe. a pair of wings, anair chamber on each of said Wings and exen tending for the full lengththereof, piping connecting these air chambers, branches on the pipingcommunicating with the drum, a pipe leading from the exhaust pipe andextending exteriorly of the fuselage along the rfi-.f top of the same toterminate at the rear end thereof.

In testimony whereof I atlix my signature.

- ISAAC E. HANSON.
